How to Calculate Terminal Velocity
What is Terminal Velocity?
Terminal velocity is the maximum speed reached by a falling object when air drag equals gravitational force. Different objects reach different terminal velocities.
Step-by-Step Guide
- 1Enter mass, drag coefficient, reference area, and fluid density
- 2The calculator applies F_drag = F_gravity at equilibrium
- 3Results show terminal velocity
Worked Examples
Input
m = 75 kg human, C_d = 1.15, A = 0.5 m² (head down)
Result
V_terminal ≈ 90 m/s (322 km/h)

Common Mistakes to Avoid
- ✕Confusing terminal velocity with escape velocity
- ✕Using incorrect drag coefficient for object shape
Frequently Asked Questions
Does terminal velocity depend on height fallen?
No, once terminal velocity is reached, speed remains constant regardless of further fall distance.
Can terminal velocity be exceeded?
Not in normal circumstances; acceleration becomes zero at terminal velocity. Powered descent can be faster.
